GCMS Scan For Unknowns
Other unknown compounds ug/L 3/7/2002 DLV
The GCMS scan, from 35 to 550 amu, reveals the possible presence of Pyridine at an estimated level of 0.12 ug/L
and with a fit of 90 out of 100; 4-Methylpyridine at 0.07 ug/L and with a fit of 90 out of 100; and Carbazole at 0.06
ug/L and with a fit of 90 out of 100. The recoverie for 2 of the 43 compounds in the LCS Standard were above their
